rockchip: puma: reorganize devicetrees to actually work and match upstream

So far the puma dts files only just included the main puma dtsi without
handling the actual baseboard and rk3399-puma.dtsi was very much
detached from the variant in the mainline Linux kernel.

Recent changes resulted in a strange situation with nonworking puma boards.

Commit ab800e5a6f28 ("arm: dts: rockchip: puma: move U-Boot specific bits to u-boot.dtsi")
moved the sdram include from rk3399-puma-ddrX.dts to new files
rk3399-puma-ddrx-u-boot.dtsi which were never included anywhere though.

Commit 167efc2c7a46 ("arm64: dts: rk3399: Sync v5.7-rc1 from Linux")
replaced the rk3399-puma.dtsi nearly completely, but in the kernel
it definitly depends on a baseboard dts to actually enable peripherals
like sd-slot, uarts, etc.

So to untagle this and bring the whole thing more in line with mainline
Linux, bring the rk3399-puma-haikou.dts over as well, drop the separate
DDR-option devicetrees and instead replace them with a puma Kconfig option
to select and include the needed DDR variant.
